title: Cytohistopathological correlation of a case of squamous cell carcinoma of gallbladder with lymph node metastasis.
abstract: Primary carcinomas of the gallbladder are rare malignancies and adenocarcinoma is the more common subtype. Primary squamous cell carcinoma of the gallbladder has rarely been diagnosed by aspiration cytology. Here, we present a case of a 62-year old female patient suffering from abdominal complaints who underwent ultrasound-guided fine-needle aspiration cytology and was diagnosed as keratinizing squamous cell carcinoma of gallbladder. The diagnosis was confirmed on subsequent histopathological examination that also revealed metastasis in the cystic lymph node. Histogenesis and biological behavior of squamous cell carcinoma of gallbladder remains a matter of debate but the role of aspiration cytology in diagnosing these lesions cannot be undermined.
